“As one of the world’s leading creators of intellectual property, including the ground-breaking television series Westworld, Warner Bros. has a deep respect for intellectual property rights. As such, the assertions by Bethesda Softworks that Warner’s Westworld mobile game improperly used source code from Bethesda’s Fallout Shelter are as surprising as they are unsubstantiated,” Warner told GamesIndustry.biz in a statement.

The App’s developer, Behaviour Interactive, has confirmed that “Bethesda’s allegations are untrue and that none of Bethesda’s code was used in the Westworld game,” and Warner maintains that it “at no time ‘induced’ Behaviour to use the Fallout Shelter code in Westworld.”
